ΕΒΥΤΕ E22-400T30D support

InTranceWeTrust last edited by

I just created a repo [https://github.com/mkoniari/MySensorsE32] with instructions / modifications for the ΕΒΥΤΕ E22-400T30D [https://www.ebyte.com/en/product-view-news.html?id=939] module (LoRa SX1278 SX1276 433MHz rf Module)

Tested with MySensors v.2.3.2 and LoRa_E32_Series_Library [https://github.com/xreef/LoRa_E32_Series_Library] v1.5.0
Hope you find it useful

@andriej Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch. We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)

Hey! If you're using ESP32 with LoRa (RFM95) and a Raspberry Pi gateway, here are some quick tips: Hardware: Heltec ESP32 + LoRa boards work great with MySensors. Power: ESP32 (~600mA) + LoRa (~120mA) can drain batteries fast—Arduino might be better. Software: Use Arduino IDE for ESP32 (try EnergyMeterPulseSensor), and set up an MQTT gateway on the RPi. Home Assistant works well for data visualization. Real-World Tips: MySensors + LoRa is great for farm/weather monitoring—checking similar projects can help.

@ZenBlizzard in case you are measuring the output with a multimeter, you will get an averaged level, since AC current waveform should be sinusoidal and overlapped with the Vcc/2->2.56V in your case. To measure the current you need a decently high sampling and some math. #define SENSITIVITY 66 // mV/A const float readings = 5; const float alpha = 2.0 / (2 * readings + 1); for (ifor = 0; ifor < 250; ifor++) { // Voltage voltageSampleRead = analogRead(V) * vccRead / 1023 - vccRead / 2; /* read the sample value including offset value*/ voltageSampleSum = voltageSampleSum + sq(voltageSampleRead); /* accumulate total analog values for each sample readings*/ voltageSampleOffsetSum = voltageSampleOffsetSum + voltageSampleRead; // Current currentSampleRead = analogRead(I) * vccRead / 1023 - vccRead / 2; /* read the sample value including offset value*/ currentSampleSum = currentSampleSum + currentSampleRead * currentSampleRead; /* accumulate total analog values for each sample readings*/ currentSampleOffsetSum = currentSampleOffsetSum + currentSampleRead; wait(1); } voltageMean = voltageSampleSum / ifor; /* calculate average value of all sample readings taken*/ voltageOffset = voltageSampleOffsetSum / ifor; reading = (sqrt(voltageMean) - voltageOffset) * 230.0 / 1.0; // read voltage / reported voltage. voltage = round_to_dp(alpha * reading + (1 - alpha) * voltage,1); Serial.println(voltage); if (voltage < 25) voltage = 0; currentMean = currentSampleSum / ifor; /* calculate average value of all sample readings taken*/ currentOffset = currentSampleOffsetSum / ifor; reading = (sqrt(currentMean) - currentOffset) / SENSITIVITY * 1000 - currentZeroOffset; // subtract no load current. if (reading < 0) reading = 0; current = round_to_dp( alpha * reading + (1 - alpha) * current,2);

When connecting an accelerometer to your PC, consider its communication protocol (I2C or SPI) and the appropriate interface device, like a microcontroller (e.g., Arduino). You may also need additional hardware for voltage adjustment or signal conditioning, depending on the sensor’s specifications.
